I think QGil actually mentioned something similar in a thread some time ago. While it should be fairly easily done as a generic application, within it's own reference system (as a 'window'), it might not be that easy to link it with actual coordinates - e.g. point at a planet or star and see the relevant star map/info. The N900 lacks a compass you have on your list, AFAIK and that makes establishing reference points hard, especially if you're not moving.
Without a compass (magnometer), I agree, this proposition is next to impossible to pull off convincingly. In fact, everything on the list is required for a seamless AR experience.
However, I suppose we'll have to wait before determining the final aspects of the hardware!
As for a AR system. It would be REALLY GOOD if someone made a comprehensive API layer on top of QT with this functionality. It would empower designers to include this type of AR functionality without having to design it ground-up every time!
YARR!

In any case it sounds doable and pretty cool (assuming the camera is able to see at least some stars tpo do the direction matching, which depends on its internals)
There's already a star map app isn't there? I wonder how hard it would be to hack heading and azimuth input into (from compass, accelerometer, starmap watching, etc.) that....
Anyway, cool idea
I completely agree! The starmap proposes many issues especially in light of hardware quirks.
Another issue with the stargazing app, is that when zoomed in, small movements of the device will result in HUGE movements across the sky. Still, I think it could be pulled off in a novel and educational way, with a clever enough interface!
As per my previous post. I would hope that it would be implemented as an API rather than an all inclusive app, as the uses are potentially far reaching!
Keep the ideas comin!
YARR!

Corrupt, eh?

Doesn't GPS functionality automatically imply compass capability? (well, a compass capability that requires GPS signal, not like a literal internal compass)

For applications as suggested above you would need a FAR more accurate compass.

Until we see some specs, it's anybody's guess. It might very well be inertial compass
